They said they had to unsolder the RSSI LED from the breakout otherwise it would do the weird counter thing. Anyway they're using the sparkfun regulated breakout for the xbee
We put in a support email to Digi and they confirmed that holding the DI or RSSI (pin 6) low during reset or powerup would put the XBEE into a 'test' mode. The LED will, indeed do this. I think it would still be possible to use the pin to drive an RSSI indicator, but you will now need a transistor to to do, driving the led directly is no longer possible. Once We got Digi's email a quick 'google' found the apnote that describes this new 'feature'. Digi mentioned that specific shields and breakout boards made by Adafruit and Sparkfun might cause this issue.
There is also the issue of the new models not being 5V tolerant, but we already took care of that.
